Important Multipurpose River Projects in India
The important multi-purpose river projects in India are helping the Ganga, Orissa and the Punjab, such as
- Bhakra-Nangal Projects

- Mayurakshi Project
Bhakra Nangal Multipurpose River Project
This multi-purpose project has been undertaken for the welfare of Punjab, Hariyana, U.P., Delhi, and the Northern parts of Rajasthan. It is India’s biggest multipurpose project. Two dams have been constructed across the Sutlej River, one at Nangal and the other at Bhakra.
The Bhakra dam, one of the highest gravity dams in the world, has been constructed across a gorge in the Himalayas. It is 518 m. long and 226 m. high. The water of the Sutlej had to be diverted into two other gorges for the construction of the dam. The reservoir is known as Govindasagar. Two hydel power stations have been set up at Bhakra dam.
The dam at Nangal is 29 m. high, from this dam, a high level canal, 64 km. long, has been constructed for the purpose of irrigation. Two hydel power stations have been, set up at Ganguwal and Kotla on the canal.
The Bhakra canal 4,464 km. long, irrigate an area of about 2.74 million hectares in Punjab, Hariyana and Rajasthan.

Besides, another 6.51 lakhs hectares are being irrigated in the Mahanadi delta with the help of weirs. It also offers facilities for navigation and development of power. Two dams constructed across this river, one at Tikkiapara and the other at Naraj, are generating hydro-electricity.
